Haemophilus
4
It can look like Bacillus or may look like coccus
Station 1 It can look like Bacillus or may look like coccus Coccobacilli
5
Station 2
6
Some of them require X & V factors ( Haemophilus influenzae)
Station 3 Different species of “Haemophilus” have different requirements to grow and make colonies. Some of them require X & V factors ( Haemophilus influenzae) Some of them need X factor only (Haemophilus ducreyi) Some of them need V factor only (Haemophilus parainfluenzae) X factor = heamatin V factor = Nicotinamide, Adenine & Dineiceotide This Bacteria grow when there are V & X factors. E.g. (H. Influenzae) This Bacteria grow when there is V factor. E.g. (H. Parainfluenzae)
7
Station 4 Only X factor X+V factors No growth Growth No growth
8
Station 5 X Factor present This is called Satellitism
Staphylococcus strip Producing V Factor H.Influenzae growing here because of presence of both X & V factors
9
Station 6 Haemophilus influenzae Infection:-
respiratory tract infections No bacteremia Haemophilus influenzae Infection:- meningitis acute epiglotitis in children (sore throught) osteomylitis & arthritis Cause bacteremia Treatment:- “Ampicilin” if beta lactamase producers “Chloramphenicol” Vaccination:- Present by Polysaccharide capsule “serotype b”

Grows on Chocolate agar
Station 7 Summary Test yourself H. influenzae H. Parainfluenzae Gram stain Type Needs (X,V factors) Grows on Chocolate agar Grows on Blood agar -ve -ve Coccobacilli Coccobacilli X + V V only Yes Yes No No Best wishes

Black color Station 14 Something like this
There is growth but this is a wrong plate
20
Station 15
21
Station 16 Corynbacterium diphtheriae Infection:-
Diphtheria “Bull neck appearance because of pharyngitis” affect: 1- nervous tissue damage (exotoxin) 2- heart muscle damage (exotoxin) 3- laryngeal obstruction 4- affect skin No bacteremia Treatment:- “Penecilin” Vaccination:- Present by toxoid “DPT vaccine” *D= diptheria toxoid *P= pertussis *T= tetanus
22
Summary Best wishes Type & “gram” stain: Stains used: Gram +ve bacilli
Station 17 Summary Type & “gram” stain: Stains used: Media used: What is used for toxogenity test? Gram +ve bacilli Gram & Albert Potassium tellurite & Loeffler’s ELEK’s plate Best wishes
23
Bordetella
24
Station 18 (coocobacili)
25
Station 19 Bordetella pertussis Infection:-
Whooping cough “due to an endotoxin” usually 1 year of age complications: bronchopneumonia, bronchiatasis & subconjuctival hemorrhage Treatment:- “Erythromycin” but only affective at early stages if beta lactamase producers “Chloramphenicol” No bacteremia Vaccination:- Present by whole killed bacteria “DPT”

اللهم إنا نسألك زيادة في الدين وبركة في العمر وصحة في الجسد
وسعة في الرزق وتوبة قبل الموت وشهادة عند الموت ومغفرة بعد الموت وعفوا عند الحساب وأمانا من العذاب ونصيبا من الجنة وارزقنا النظر إلى وجهك الكريم دعواتكم يا شباب
